The main source of reactive oxygen species (ROS) in the cell is mitochondrial respiration. It was first shown that isolated mitochondria from the liver and heart of animals are active sources of hydrogen peroxide (H2O2), which is capable of diffusing into the cytosol.
The main source of reactive oxygen species (ROS) in the cell is mitochondrial respiration. It was first shown that isolated mitochondria from the liver and heart of animals are active sources of hydrogen peroxide (H2O2), which is capable of diffusing into the cytosol [1,2]. It is assumed that in the heart and liver of rats, mitochondrial H2O2 production accounts for approximately 0.5% of the total organ O2 consumption when mitochondria use substrates such as succinate or malate-glutamate, and about 0.15% when palmitoyl-carnitine is used as a substrate. Somewhat later, it was established that the precursor of mitochondrial H2O2 is superoxide (O2·⁻), and its main source in mitochondria was identified as the autoxidation of ubisemiquinone (UQH·) [2,3]. It is currently known that O2·⁻ is formed not only during the autoxidation of UQH·, but also due to electron leakage from complexes I, II, and III of the electron transport chain (ETC) to molecular oxygen.
Significant progress in the study of mitochondrial free radical processes was the demonstration of the kinetics of O2·⁻ formation in the mitochondria of living cells and organs. Thus, in cell cultures loaded with a new O2·⁻ biosensor (yellow fluorescent protein), researchers observed fluorescence bursts in individual mitochondria or groups of functionally connected mitochondria, reflecting O2·⁻ production [4]. The distinctive feature of this fluorescent protein was that it did not react with other ROS in the cell, such as H2O2, peroxynitrite, hydroxyl radical, or NO [4]. The result of O2·⁻ release was the opening of mitochondrial permeability transition pores (mPTP) not associated with Ca²⁺ release. O2·⁻-initiated mPTP opening was associated with ETC activity and was ATP-dependent. The generation of O2·⁻ correlated with a transient decrease in membrane potential, matrix acidification, and mitochondrial swelling. Anoxia or moderate hypoxia reduced the frequency of O2·⁻ fluorescence flashes in cardiomyocytes, highlighting the role of selective ROS production in the cell. This process utilizes scavenging and detoxifying systems in signaling cascades, as well as kinases, phosphatases, membrane channels, and transporters. However, some researchers [5] have disputed the idea that mitochondria are the main producers of O2·⁻ and H2O2 in mammalian cells, arguing that the generation of free radicals by mitochondria may be an artifact resulting from disruption of mitochondrial membrane integrity during isolation [6]. These same authors showed that disruption of redox coupling at the ubiquinone/cytochrome bc1 site, which depends on the physical state of the inner mitochondrial membrane, is accompanied by electron leakage and ROS generation.
The second source of ROS in the cell comprises certain mitochondrial enzymes, in particular two enzymes of the Krebs cycle — aconitase and α-ketoglutarate dehydrogenase — as well as pyruvate dehydrogenase, glycerol-3-phosphate dehydrogenase, dihydroorotate dehydrogenase, monoamine oxidases A and B, and cytochrome b5 reductase.
The third important source of mitochondrial ROS production is mitochondrial NO synthase (mtNOS) [7,8]. In hepatocytes and cardiomyocytes, NOS is localized inside the mitochondria, whereas in endothelial cells it is associated with the intermembrane side of the outer mitochondrial membrane [8].
The majority of O2·⁻ (70–80%) formed in the mitochondrial ETC enters the matrix, while 20–30% enters the intermembrane space. Previously, two main pathways of O2·⁻ production in the mitochondrial ETC were described in detail: 1) as a result of the autoxidation of intermediate semiquinones (UQH· for the redox pair ubiquinol/ubiquinone: UQH· + O₂ → UQ + H⁺ + O2·⁻) [2], and 2) as a result of the oxidation of the coenzyme FMNH2/FMN by NADH dehydrogenase (FMNH· + O₂ → FMN + H⁺ + O2·⁻) [9]. It is known that semiquinones are non-enzymatically oxidized by molecular O₂, forming O2·⁻. It has been proven that ubisemiquinone is the main quantitative source of one-electron reduction of O2 in the mitochondrial ETC [10].
The formation of H2O2 in mitochondria is modulated by their metabolic state and the intramitochondrial concentration of NO. Thus, H2O2 production in metabolic state IV is approximately 4–5 times higher than in metabolic state III and amounts to 0.3–0.8 nmol H₂O₂·min⁻¹·mg protein⁻¹ in state IV and only 0.05–0.15 nmol H2O₂·min⁻¹·mg protein⁻¹ in state III [11]. Ion fluxes across the inner mitochondrial membrane have a strong effect on the rate of H2O2 formation, indicating a regulatory role of the membrane potential in the process of UQH· autoxidation [12].
The synthesis of nitric oxide catalyzed by mtNOS occurs in an enzymatic reaction that requires arginine, NADPH, and O2 as substrates. As a result of the reaction, citrulline, H2O, and NO are formed (NADPH + arginine + O₂ → NADP⁺ + H2O + citrulline + NO). Three different genomic NOS isoforms are known: neuronal NOS (nNOS or NOS1), inducible NOS of macrophages (iNOS or NOS2), and endothelial NOS (eNOS or NOS3). Two independent groups of researchers have established that one of the sources of nitric oxide is the mitochondria [13,14]. Mitochondrial NO is produced by one of the isoforms of NOS — mitochondrial nitric oxide synthase. Physiological production of NO by the enzyme is interrelated with the regulation of cytochrome c oxidase activity: an increase in NO levels reduces cytochrome c oxidase activity through S-nitrosylation of cysteine residues in complexes IV and I [10,15]. In the uncoupled state, endothelial NOS (eNOS) generates the superoxide anion radical [16]. Uncoupling does not require dissociation and monomerization of the enzyme; it most likely occurs as a result of substrate and tetrahydrobiopterin deficiency, leading to facilitated superoxide generation through a NO-dependent mechanism and accompanied by peroxynitrite formation with a decrease in NO levels. Numerous pathological conditions lead to eNOS uncoupling; for example, this was clearly demonstrated in endothelial dysfunction [17].
Subsequently, mitochondrial NO synthase was identified as a variant of post-translational modification of nNOS involving its myristoylation and phosphorylation [18]. For the enzymatic reaction of NO synthesis to occur, the concentrations of NADPH, arginine, O₂, and Ca²⁺ in mitochondria must be sufficient. Mitochondrial and submitochondrial preparations synthesize NO at a rate of 0.25–0.90 nmol·min⁻¹·mg protein⁻¹. It was calculated that the intramitochondrial steady-state concentrations of NO are 50–200 nM [10], and the NO release measured electrochemically in isolated mitochondria after the addition of Ca²⁺ amounted to 29 nM [20]. Under physiological conditions, tissue O2 saturation is approximately 25 µM, and the mitochondrial [O2]/[NO] ratio is 150–300, which supports 25–50% inhibition of cytochrome oxidase [21]. It has been shown that NO produced by NO donors or mtNOS inhibits complex III of the ETC (50% inhibition of electron transfer between cytochromes b and c occurs at an NO concentration of 0.2–0.4 µM) and increases the production of O2·⁻ and H2O2 in mitochondria and submitochondrial particles [22]. This mechanism is often involved in the molecular mechanisms of neurological diseases. However, controversies regarding the existence of mtNOS still remain [19].
Intramitochondrial reactive oxygen and nitrogen species, such as O2·⁻, H2O₂, NO, and ONOO⁻, are potential activators of oxidative stress, which is considered a factor determining the molecular mechanisms of tissue dysfunction in inflammation, neurological diseases, and aging. Two of them, O2·⁻ and NO, are free radicals; however, due to their low reactivity, they do not participate in branching reactions but only in chain-terminating reactions, accompanied by the formation of H2O₂ and ONOO⁻. The latter two compounds are potentially dangerous because, after homolytic cleavage, they participate in the generation of the highly reactive hydroxyl radical (·OH) and the free radical NO2·, which is involved in protein nitration [23].
The formation of NO and H2O2 in rat liver mitochondria has an exponential dependence on the magnitude of the membrane potential [24]. In the mitochondrial matrix, the metabolism of NO and O2·⁻ is not limited by diffusion in the reaction leading to the formation of peroxynitrite (NO + O2·⁻ → ONOO⁻) [25]. This oxidative pathway of NO utilization (80%) is the main one in metabolism and consumes only a small portion of O2·⁻ (15%), whereas the reduction of NO by ubiquinol and cytochrome oxidase accounts for approximately 20% of NO utilization in mitochondria [10].
Peroxynitrite is a strong oxidant that, in its charged form, rapidly diffuses from the intramitochondrial space. Peroxynitrite irreversibly inhibits complexes I and III [26]; a significant increase in ONOO⁻ levels in mitochondria leads to their dysfunction and cell apoptosis. The level of ONOO⁻ in the mitochondrial matrix under physiological conditions is in the range of 2–5 nM [10], while levels above 20–30 nM are considered cytotoxic. Mitochondrial dysfunction is associated with excess NO and ONOO⁻ during ischemia/reperfusion, inflammation, and aging [27]. In the mitochondrial matrix, peroxynitrite rapidly reacts with CO₂ to form the ONOOCO₂⁻ adduct (k = 6 × 10⁴ M⁻¹s⁻¹), which also participates in the nitration and oxidation of proteins and lipids. Formation of the adduct reduces the steady-state level of ONOO⁻ from 30 nM to 2 nM [28] and is considered one of the pathways for detoxification of mitochondrial ONOO⁻ at high mitochondrial CO2 concentrations (1 mM).
Mitochondria have a multi-level system of enzymatic and non-enzymatic antioxidant defense, which ensures the detoxification of produced ROS. Enzymatic components include manganese-containing superoxide dismutase (MnSOD) [29], catalase, glutathione peroxidase, and phospholipid hydroperoxide glutathione peroxidase (which reduces hydroperoxides of phospholipids, lipoproteins, and cholesterol esters) [30], as well as enzymes involved in the regeneration of oxidized forms of small antioxidant molecules, such as glutathione reductase, thioredoxin reductase, glutaredoxin, and peroxiredoxin [31]. For the regeneration of glutathione-by-glutathione reductase and the restoration of thioredoxin 2 by thioredoxin reductase, the presence of NADPH is required. Mutations in the genes corresponding to these enzymes are associated with certain types of pathology, such as idiopathic cardiomyopathy, neurological diseases, impaired glucose metabolism, and tumors [32,33].
Non-enzymatic components of antioxidant defense include a number of hydrophilic and lipophilic free radical scavengers, such as cytochrome c, α-tocopherol, ascorbic acid, the reduced form of coenzyme Q10, and reduced glutathione (GSH).
The main part of mitochondrial O₂·⁻ diffuses into the matrix, where it interacts with intramitochondrial MnSOD, which catalyzes the reaction 2O2·⁻ + 2H⁺ → O₂ + H2O2. The steady-state concentrations of O2·⁻ in the mitochondrial matrix are 0.2–0.3 nM at a content of 10–40 µM MnSOD reactive centers [31]. O2·⁻ diffusing into the intermembrane space reacts with cytochrome c located on the outer side of the inner membrane and with Cu,Zn-SOD of the intermembrane space [34].
Glutathione peroxidase catalyzes the conversion of H2O2 and the reduction of lipid hydroperoxides (ROOH) with the participation of reduced glutathione [H2O₂ (ROOH) + 2GSH → GSSG + 2H2O (ROH + H2O)] and is a unique enzyme that uses H2O2 as a substrate in the mitochondria of most mammalian organs, with the exception of the heart, where mitochondrial catalase has been described [35]. Due to the activity of glutathione peroxidase, 60% of H2O2 formed in the mitochondria is metabolized, indicating its important role in H2O2 detoxification and in the reduction of mitochondrial hydroperoxides [36]. GSH deficiency is associated with widespread mitochondrial dysfunction leading to cell damage [37]. The functioning of glutathione peroxidase requires a continuous supply of GSH to the mitochondria from the cytosol, where it is synthesized. A separate enzyme, NADPH-dependent glutathione reductase located in the mitochondrial matrix, is highly active and maintains the GSH/GSSG ratio in a highly reduced state [38].
Thus, ROS generation in structurally and functionally intact mitochondria is balanced by the antioxidant defense system, which limits the spread and bioavailability of ROS. A reduction in the level of antioxidant defense in mitochondria is a prerequisite for increased ROS production, the development of oxidative stress, and subsequent mitochondrial dysfunction.

Dear Maria Emerson, Editorial Coordinator of International Journal of Clinical Case Reports and Reviews, What distinguishes International Journal of Clinical Case Report and Review is not only the scientific rigor of its publications, but the intellectual climate in which research is evaluated. The submission process is refreshingly free of unnecessary formal barriers and bureaucratic rituals that often complicate academic publishing without adding real value. The peer-review system is demanding yet constructive, guided by genuine scientific dialogue rather than hierarchical or authoritarian attitudes. Reviewers act as collaborators in improving the manuscript, not as gatekeepers imposing arbitrary standards. This journal offers a rare balance: high methodological standards combined with a respectful, transparent, and supportive editorial approach. In an era where publishing can feel more burdensome than research itself, this platform restores the original purpose of peer review — to refine ideas, not to obstruct them Prof. Perlat Kapisyzi, FCCP PULMONOLOGIST AND THORACIC IMAGING.

Dear Mayra Duenas, Editorial Coordinator of the journal IJCCR, I write here a little on my experience as an author submitting to the International Journal of Clinical Case Reports and Reviews (IJCCR). This was my first submission to IJCCR and my manuscript was inherently an outsider’s effort. It attempted to broadly identify and then make some sense of life’s under-appreciated mysteries. I initially had responded to a request for possible submissions. I then contacted IJCCR with a tentative topic for a manuscript. They quickly got back with an approval for the submission, but with a particular requirement that it be medically relevant. I then put together a manuscript and submitted it. After the usual back-and-forth over forms and formality, the manuscript was sent off for reviews. Within 2 weeks I got back 4 reviews which were both helpful and also surprising. Surprising in that the topic was somewhat foreign to medical literature. My subsequent updates in response to the reviewer comments went smoothly and in short order I had a series of proofs to evaluate. All in all, the whole publication process seemed outstanding. It was both helpful in terms of the paper’s content and also in terms of its efficient and friendly communications. Thank you all very much. Sincerely, Ted Christopher, Rochester, NY.
